Urolithiasis, 2017
Since the introduction of ESWL, PNL and URS during the early 1980s the application rate of ESWL has declined while those of PNL and URS have increased. This is mainly due to the facts that instruments and techniques for Intracorporeal Lithotripsy (IL) have made a continuous progress.

Extracorporeal shock-wave lithotripsy (ESWL) has been applied to patients with gallstones since the mid-1980s. Lithotriptors differ by their means of shock-wave generation, the mechanisms by which they are coupled to the patient, and their imaging systems.

Journal of Endourology, 2000
Holmium:YAG lithotripsy of uric acid calculi produces cyanide. The laser and stone parameters required to produce cyanide are poorly defined. In this study, we tested the hypotheses that cyanide production: (1) varies with holmium:YAG power settings; (2) varies among holmium:YAG, pulsed-dye, and alexandrite lasers; and (3) occurs during holmium:YAG ...

Current Opinion in Urology, 2002
All literature related to laser lithotripsy published within the past year was reviewed. Salient articles have been reviewed and grouped according to safety issues, efficacy, comparison studies, biliary applications or future directions.There is no evidence of renal deterioration after holmium:yttrium-aluminium-garnet lithotripsy.

Lithotripsie intrahepatischer Gallensteine
DMW - Deutsche Medizinische Wochenschrift, 2008After placement of a T-drain near some intrahepatic gallstones their fragmentation was successfully accomplished by extracorporeal shock-wave lithotripsy in a 35-year-old man. The fragments passed through the outside via both the drain and stool. A few fragments which remained in the T-drain and the distal bile duct were easily flushed out later.

Focused Ultrasound and Lithotripsy
2016Shock wave lithotripsy has generally been a first choice for kidney stone removal. The shock wave lithotripter uses an order of microsecond pulse durations and up to a 100 MPa pressure spike triggered at approximately 0.5-2 Hz to fragment kidney stones through mechanical mechanisms. One important mechanism is cavitation. We proposed an alternative type

Laser lithotripsy is an excellent method of fragmenting those biliary stones that cannot be removed easily by less technically advanced methods such as basket extraction. The energy can be delivered through fine flexible fibers, around 200 to 320 microns in diameter, that can be passed through the channels of a variety of small endoscopes.

The Journal of the Acoustical Society of America, 1988
The pressure amplitudes of the shock waves used in lithotripsy far exceed thresholds for transient cavitation. Where appropriate nuclei exist within the body, it is highly probable that bubbles will form and collapse violently, giving rise to potentially undesirable side effects of the treatment.

Ultrasonic Lithotripsy in the Ureter
Urologic Clinics of North America, 1988With the increasing range of indications for extracorporeal shock-wave lithotripsy, "easy" cases of ureteroscopic stone removal have vanished. Clinical experience with ureterolitholapaxy has proved the method safe, effective, and reliable in the hands of the experienced urologist.

The Surgeon and Biliary Lithotripsy
Archives of Surgery, 1989Surgeons have been receiving the news of lithotripsy for gallstones with anxiety and some disdain. The initial pieces of the story have seemed to be a rewrite of the advent of endoscopy, biliary stenting for pancreatic cancer, endoscopic polypectomy, and percutaneous drainage of abdominal abscesses.
